Eastman and Laird, using money from a tax refund, printed a limited
edition of 3,000 copies of TMNT that was distributed at
the comic convention at Portsmouth, New Hampshire in 1984. This
led to more comics as well as a video game, and then more comics.
Laird bought out Eastman's share of the TMNT in 2000 and
continues with his own company Migage Studios.

Synopsis:

Teenage Mutant Ninja Turtles: The Movie is the live-action, feature
film adaptation of the cult comic book and the popular animated
television show. After prolonged exposure to radiation, four teenage
turtles--Michelangelo, Raphael, Leonardo, and Donatello--have mutated
into ninjas and have begun living in the sewers of a large city.
Under the guidance of a ninja master Splinter the Rat and television
reporter April, the Turtles embark on a mission to run crime out
of the city and battle the warlord Shredder. The Turtles have been
designed by Jim Henson Productions and effortlessly fit into the
live-action surroundings.
